Buy a small 4 cyl pickup. Equip it with extra deep cycle marine batteries and both a small solar cell (+/-) 300watt trickle charger. Combine that with a 800 watt AC power inverter and a propane heat soarce. These can be installed in a high profile camper top. throw in a nice memory foam mattress, a cooler, camp stove, SW radio,.308 cal rifle, fishing rig, a few tools and a plan. You are now ready for what may come your way. Remember also, the more you have in your head , the less you will need to take along. ;)
